SCAFFOLDING BRACKET.

. Application filed April 2?, 1922. serialllo. 566,954.

To all whom z't may concern:

Be it known that I, EDSON BBEX, a citizen of the United States, residing at Bucyrus, in the county of Crawford and State of Ohio, have invented certain new and useful Improvements in Scaffolding Brackets, of which the following is a, s ecification.

This invention relates to hracket devices for supporting builders caffolding or staging for use on buildings in the course of erection or being repaired, and has for one of its objects to provide a device of this character simple in construction, easily applied to and removed from buildings, inexensive to manufacture, and which may be olded into relatively small space for shipment or storage.

With these and other objects in view the invention consists in certain novel features of construction as hereinafter shown and described and then specifically pointed out in the claim, and in the drawings illustrative of the preferred embodiment of the invention:

Figure 1 is a side elevation of the improved bracket. v

Fig. 2 is a detail plan view of the support engaging jaw.

Two or more of thebracket devicesare employed, and spaced to correspond to the lengths of the staging planks, but one bracket only is shown for illustration.

The improved bracket device comprises a main horizontal supporting member or beam B, preferably of a section of an l..-bar hav-.

ing a head member A attached as by rivets at the inner end and with the other or outer end upturned as at l to form a stop to prevent the disnlacement of the platform or planking of the staging or scafi'olding which rests upon two or more of the brackets, as before stated.

The inner end of the head member A pro-- vides a clamping face having a spur K, and projecting rearwardly from the inner end of the head member Axis an angle shaped jaw member A, formed of a long and short arm and with the long arm integral with and offset with respectto the head member A. The short arm of the jaw member A opposes and is spaced from the clamping face of the head member A. The jaw memher A is adapted to overlap a stationary support, by way of example, one of the studat another point, a verystron dings of the building being erected as illustrated in dotted lines at J. Operating through the short arm of the jaw member A is a clamping screw G, having its outer end provided with a hinged turning handle H and its inner end formed with a swivelled head F, opposing the spurred clamping face of the headmember A and formed with a plurality of spurs L.

By setting up the jaw member A and head member A, in the manner as tated, the horizontal supporting member or beam B may be firmly clamped to the'studding J or other support as is obvious.

' The head member A is formed with a depending ear M to which a linkE'is pivoted at N, and pivoted'at P to the free end of the link N is another link D, the latter hav-.

ing a lateral spur Q to beembedded in the supporting member J when the bracket is installed on the building.

" Pivoted at one end at R, to the beam member B and at the,other end at S to the link D,is a brace C.

When thus constructed and the-partsar- 4 ranged as in full lines in Fig. 1, and the jaw A coupled to the member J at onepoint and the spur Q embedded in the member J bracket device is produced, which may be readily installed where required tosupport a staging or scaffolding, and as readil disconnected and the parts C, D and E folded 'up against the beam portion B and its jaw portion A, as indicated by the dotted lines, which represents the device partly folded or collapsed, for shipment or storage, or to facilitate the changing of thebrackets from one part of a building to another.

The head member A and its jaw A are of metal, preferably malleable iron or cast steel, the beam member B and brace C of IL. metal, preferably steel, While the links E and D are of metal also preferably steel, all the parts'being as light as possible .consistent with the strains to which they are to be subjected when in use. i

The parts may be of any size or proportion and of any suitable material.

The preferred embodiment, of theinvention is disclosed in the drawings and set forth in the specification, but it will be un derstood that modifications within the see c r the claimed invention may be made in t e.

and rigid ice 7 prising a horizontally disposed supporting beam having an up-turned outer end, a rearwardly extending head member secured to the inner end of said beam' and provided with a spurred clamping face and furtherwith a depending ear at its inner end; an l.-

i shaped jaw member integral with and projectlng rearwardly from said head member and includingia long and a short arm, a vertically disposed foldable'supporting member formed of an upper and a lower section pivotally connected together, said upper section having its upper end pivotally connected with said ear and said lower section having its lower end spurred," an inclined brace member having its upper end pivotally connected to said beam in proximity to the outer end of the latter and having its lower end pivotally connected to the lower end of said lower section, and a clamping screw threadably engaging with the short arm of the jaw member and provided'with a spurred clamping head opposing said spurred clamping face.
